This invention relates to demountable rims, and is more especiallydirected to a tie plate which has the additional functions of being botha driver and a device for the application of a rim-contracting tool.

We are'aware that it is not broadly new to provide-adevice which hasthese several functions, but we believe that our device is animprovement in'the Way of economy in manu facture, effectiveness as atie and driver, and adaptability for a rim-contracting tool. This Willbe more fully explained as the detailed construction is described.

a designates the fixed rim; 6 the demountable rim; the fixed rim isprovided with the usual bolts 0. These bolts take the nuts 65 Which maybe used to bear against the clamping lugs 6. However, the loose lugs aresim ply shown as one form of securing device, for obviously the attachedlug type could be equally well used, but in such a case the driverfeature of the tie device would not be needed.

A tie plate in the form of a stamping made of scrap steel, is providedwith a round ed up end or flange h and a pair of lateral ears 9, whichare under-cut at their outer ends to provide the tool-receiving gulletsi. Their inner ends j are curved to fit over the bolts 0 and inconnection with a stud 7a to form a straddler for the bolt, whicheffects the driving connection between the demountable rim and the fixedrim.

connection is'ordinarily necessary with loose lug construction.

A tire contracting tool such as shown' in Fig. 1, is arranged toco-operate with the rim end fastening device. 'This is nicely shown 5 inFigs. 5 to 10 inclusive; The toolcomprisesv a bifurcated lever m and aswinging loop 12. The ends of the lever are connected by a strut rod' orfulcrum 0.Referring to Fig. 5, the loop a hooks in the gullets 2' whilethe strut 0- rod 0 bears against theturned up end it of the tie plate.Pulling up on the lever m, this lever fulcrums on the ends of the loopnand acts as a lever of the first order, and the strut 7, rod 0 is theload endwhich is driven in under the turnedup end it ofthe' tie plate.This forces the strut rod in under the tie plate and against the stud isas shown-in Fig. 61 Thereupon the character of the lever changes. Thestrut rod 0 now becomes the fulcrum member and the load is transferredtothe'loop.* Further lifting of the lever lifts the tie plate end of therim, forces it off'the'stud is and starts to lift this end of the rimover the stud, asis clearly shown in Fig. 7. In this lifting action onehas to overcome the resistance of'the' rim, which tends to resist suchdistortion. However, in forcing the tool into the position against thedemountable rim shown in Fig. 9, the load is forcedto-ride up the faceof the tool, as shown in 11" as A and isthrown over" a center, or apoint of maximum distortion" of the rim that appears to be. shortlyafter the loop and gullet' pass over therim" radius, which passesthrough the fulcrum of the lever. Apparently here the tool allowsthe rimend to drop back towards the other'rim end and the rim reaches theGXtIGHIGOf dis-'- tortion,' being carried'radially inward further thanat any other point'inthe action of thelev'er. Therefore, afterpassing-'th'is'point while itis caused to overlap the other'end of therim more, nevertheless the actual distor tion of the rim is less andconsequently the rim itself will force the lever down and keep it i'nlocked position; V

To re-expand the rim, the lever is pulled: back over the center'untilthe tie plateendof the'rim rests on the top of thestud', as-shown' inFig. 9.

Furthermore, while the. inner ends of the lateral ears form a portion ofthe driver, the opposite ends of the ears are recessed'for the receptionof a tool. This permits economy in manufacturing, and does notrequireseparate punching or drilling operations for forming a tool-receivingpeia
